3. Released on the C64 1986, the game got a beautiful remake for it's conversion to the Amiga.

4. Originally released on the Atari ST which had the better version with a full set of alien language sounds. Noted here due to the lack of an Atari ST section and the games very original style and gameplay.

9. Known as Contra III: The Alien Wars in North America and as Contra Spirits in Japan. The European version is identical to the American release, but replaces the original commandos with robotic soldiers codenamed RD008 and RC011.
